tached to a flexible support;

Fig. 4 is an elevation view of the socket before it is secured to itssupport and with the ca removed; and

i 5 is a side elevation of the back plate.

Re erring to the drawin there is shown a separable fastener whic isparticularly useful as a curtain fastener or as a glove fastener,although it may be used for many other purposes where a snap fastener isrequired.

The stud illustrated is of the well known hollow pressed type, having ahead 1, a neck 2 and a base portion 3. The base portion is crimped overthe head 4 of an attaching screw 5, which is secured to a rigid support6, such as the body of an automobile, as shown in The socket is securedto the curtain 7 and includes a stud-en aging part having a base portion8 and a tu ular portion pressed from the center of the base portion andslit throughout its entire length and partly into the base portion 8 toprovide a plurality of resilient fingers 9. These fingers are providedat their free ends with reversely ent neck-engaging portions 10'preferably bent inwardly to engage the neck of the stud. The resilientfingers are substantially parallel with the axis of the stud and arefree to expand to a limited extent, as more fully hereinafter described.The base portion 8 of the stud-en aging part also presents at its outerperip cry a prong-receiving portion, which'comprises an anvil portion 11and a clench portion 12, to which is secured a cap member 13 (Fig. 2)for concealing the underlying portions of the socket This cap may or maynot be used, but it Is preferred to use it so as'to provide a neat andfinished appearance to the socket when viewed from the outer face of thecurtain 7.

While the socket may be secured to the curtam 7 in any suitable manner,it is preferred to secure it thereto so that the base portion 8, of thestud-engaging part, will overlie a portion of the outer face of thecurtain 7.

The resilient fingers 9 pass through an aperture 14 in the curtain 7 andextend slightly beyond the inner face of the curtain 7. A back plate 15is applied'to the inner face of the curtain and is secured to thestudengaging part by a plurality of attaching prongs 16. These prongsproject from the,

periphery of the back plate (Fig. 5) and extend through the curtain 7where they are bent outwardly and downwardly by the anvil portion 11against the clench portion 12, thus securin all the parts of the socketto the curtain. be back plate also presents an aperture 17 through whichthe resilient fingers 9 protrude, and which is large enough in diameterto permit the resilient fingers to expand during engagement anddisengagement with the stud. The wall, surrounding the aperture, backsupports the resilient fingers and prevents too great expansion thereof,when strain is exerted thereon. Thus the resilient fingers are backsupported by the back plate 15 so that the fastener cannot be separatedby resolution of forces due to lateral strain exerted upon the curtain7.

into base portion 8 (Fig. 4) sufficient distance to permit the fingersto bend upon straight lines, passing through the flat base portion 8.between the slots 18, during contraction and expansion thereof. Byextending the slots to the base 8, the fingers 9 may bend more easilywith less possibility of their becoming set because they do not bendupon the curved portion as would be the case if the slots terminated ator before reaching the base portion. Thus there is provided a socketwhich is strong and durable and which is simple and inexpensive tomanufacture.

While there is shown and described a preferred embodiment of theinvention, it will be understood that ch-an es involving omission,substitution, alteration and reversal of parts, and even changes in themode of operation, may be made without departing from the scope of theinvention, which is best defined in the appended claims.
